A sonic source, located in a uniform medium, emits waves of frequency `n`. If intensity, energy density (energy per unit volume of the medium) and maximum speed of oscillations of medium particle are, respectively, `I`, `E` and `u_0` at a point, then which of the following graphs are correct?

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
C
Energy densit `(E)=(1)/(v)=2pi^(2)rhof^(2)A^(2)`
`v_(max)=omegaA=2pifAimpliesEprop(v_(max))^(2)`
i.e. Parabola.
